摘　　要：针对传统的能源数据监管存在的数据可信度低、难以差异化共享以及数据确权难等问题,提出了一种基于联盟链的能源数据可信监管模型.依托数据资源目录建立目录区块链,链上存储目录数据,链下存储实际能源数据,实现了数据的链前监管.在实际数据共享阶段,将访问过程记录上链,并添加索引结构,方便数据的查询,实现了数据的链上监管.监管部门可结合监管链信息验证链下数据的真实性,从而为能源数据的监管提供了思路.Aiming at the problems of low data reliability,differentiated sharing and data right confirmation in traditional energy data supervision,this paper proposes a trusted supervision model of energy data based on alliance chain.This scheme relies on the data resource directory to establish a directory blockchain,store directory data on the chain,and store actual energy data off the chain,realizing the pre-chain supervision of data.For the actual data sharing stage,the access process records are uploaded to the chain,and an index structure is added to facilitate data query and realize the on-chain supervision of data.The regulatory authority can verify the authenticity of off-chain data by combining the chain of custody information,thus providing ideas for the supervision of energy data.
